5. Answer the following questions about the following sequence: 3+5n2 a = " n2+n a) Use GeoGebra to sketch the graph of the terms of the sequence. Use the graph to make an inference about the convergence or divergence of the sequence. b) Use GeoGebra to nd the limit of the sequence and determine if the sequence converges or diverges. c) Compute the limit of the sequence by hand techniques and determine if the sequence is convergent or divergent. Compare your answer with part b
